Cancer therapeutics has seen an emergence and re-emergence of two metabolic fields in recent years, namely bioactive sphingolipids and glycolytic metabolism. Anaerobic glycolysis and its role in cancer has been recognized in cancer biology over 90...

Heart failure is recognized as a major cause of death among diabetics. In type I and II diabetes, glucose uptake, glycolysis and pyruvate oxidation are impaired, and fatty acid utilization increases. These alterations in metabolism contribute...

Pituitary adenylate cyclase-activating polypeptide (PACAP) is a 38-amino acid C-terminally α-amidated peptide that was first isolated from ovine hypothalamic extracts on the basis of its ability to stimulate cAMP production in anterior pituitary...

The focus of my dissertation work is to study the gold-catalyzed intramolecular and intermolecular cyclizations involving oxonium intermediates towards the application of synthetically interesting frameworks under ambient conditions and developing...

Nuclear Factor of Activated T-cells (NFAT) is a calcium-responsive transcription factor that orchestrates immune response and cardiovascular development. NFAT is also present in neurons and glia from the Central Nervous System (CNS) where it...

Complement, an early recognition system of innate immunity that senses local tissue damage and infection, cross-talks with and regulates other signaling systems, including Toll-like receptor (TLR) pathways. In the context of periodontitis,...

In the retina, the receptive fields (RFs) of most neurons are comprised of an excitatory center and a suppressive surround. Retinal ganglion cell (RGC) RF center excitatory input arises from bipolar cell (BC) inputs, while their surround arises...

Research over the past twenty five years has led to the development of the hypothesis that colorectal cancer is caused by the accumulation of mutations in tumor suppressor genes and proto-oncogenes. The last ten years has also revealed that the...

Bcl-2 proteins are major regulators of cellular responses to various apoptotic stimuli. Among them, overexpression of the anti-apoptotic BcI-2 protein BcI-xL modulates organelle-specific apoptotic pathways. To understand the mechanisms by which...

c-Myc dysregulation is one of the most common abnormalities found in human cancer. MicroRNAs (miRNAs) are functionally intertwined with the c-Myc network as multiple miRNAs are regulated by c-Myc, while others directly suppress c-Myc expression. In...

Epithelial Ovarian cancer (EOC) is the leading cause of gynecological cancer death in the USA. Recurrence rates are high after front-line platinum chemotherapy and most patients eventually die from platinum-resistant disease. P53 plays an important...

The immune system is of profound importance for host survival due to its ability to clear many acquired diseases. In case of infections and cancer, disease arises due to under-performance of immune system. Whereas in autoimmunity and...

Cardiovascular disease is the leading cause of death worldwide. When a myocardial infarction occurs, scar tissue compensates the damaged myocardial tissue. This scar tissue increases the stiffness of the heart tissue, reduces the heart’s...

Age-related alterations in innate immunity are poorly understood. The identification of those mechanisms, which are dysfunctional in old age, will shed light on potential therapeutic strategies for chronic inflammatory diseases prevalent in the...

Human exposure to mercury has been shown to cause a number of adverse health outcomes, predominantly neurological effects. The developing fetus is most susceptible, and even low levels of exposure have been shown to produce nervous system deficits....

This thesis is divided into two parts below. Part I Adriamycin (ADR) can produce nephrotoxicity in rodents. The underlying mechanism may relate to ADR induced oxidative stress. In this study, we used transgenic mice (NMT3), which over-expressed the...
